Then I guess he would hate an old co worker of mine who always used a single pole switch for the 240volt air handler

An error like that could put you out of business if someone (anyone) was injured because of negligence, I suspect.

IMO, that is just adding more potential failure points (four more terminals and the female&male contact points on the pullout). All modern breakers are HACR so I see no purpose.

HVAC equipment also includes internal or "hidden" (from the user) controls and switches that are necessary for proper system operation. Just knowing that these items exist is the first step in diagnosing & repairing an air conditioner, heat pump, refrigerator, freezer or other HVACR equipment that is not working or not working properly..

Do not set the thermostat for cooling below 68 degrees. This can cause a multitude of problems with your air-conditioner, including freezing up.

Remember to turn off your humidifier for the summer cooling system..
